I'm looking for someone to shed a little light on this for me...
I wish to unlock my Xperia S boot loader (Service info says "YES").
But, I also want a way to revert the phone completely back to stock.
So I need to ensure I can relock the boot loader, and DRM etc will function as normal.
I need a few things
Whats the best way to unlock my boot loader?
If possible, can I Relock the boot loader?
Once Relocked, and stock ROM applied, is it fully functional? (DRM and TrackID working etc)
Sorry for the double post...
Just wondering if anyone could help or answer?
I've now rooted my SXS, still would like to know about unlocking and Re-locking the bootloader.

Right now I have the 4.0.4 Android( stock version) of the xperia j with locked bootloader and I've rooted-it and I've also installed the CWM.
I would like to install Cyanogen Mod 10.1 but since I have the 11.0.A.7.5 firmware I have locked bootloader and I can not flash it.
My question is if I can flash an older stock firmware and by doing so will I be able to unlock my bootloader?
From what I understand right now since I have a locked bootloader I can only flash stock ROMs so if that is correct than can I just flash an older stock ROM, one that will allow me to unlock my bootloader and than flash CM 10.1 on my Xperia J?
And another question- I know that by unlocking the bootloader I will also loose my warranty but from searching the XDA forums I saw that I can make a backup copy of my stock ROM and flash it to relock the bootloader again. Is that accurate ?
Thanks in advance for your help!
First is your bootloader unlockable. Then you can unlock on any firmware via sonys website. I dont think there's a cm10.1 released for j. If you unlock your bootloader you will loose DRM keys forever even if you relock they will still be gone that's how Sony will know your bootloader was unlocked.
It is not unlockable, that is why I wanted to flash another version of a stock ICS.
Won't that allow me to unlock the bootloader ?
From what I understood right now I can only flash stock Roms with the locked bootloader, is it correct or since I have the "NO" status at the bootloader I can't even do any of that ?
So I tested lohzocum's kernel and it works, however when I tried restoring the TA partition, it wouldn't boot anymore. And I re-flash the stock KK firmware, it said Bootloader unlocked allow: Yes. So obviously my bootloader was locked again. Any way to avoid bootloader relocked ?

If you restore TA partition it relock your bootloader...
There's no way to avoid it ?

Why would you restore TA with unlocked bootloader ? it doesn't have any meaning .
It'd be nice to be able to restore the DRM keys but not relock the bootloader.
Especially after reading stuff like this: http://www.gsmarena.com/unlocking_the_sony_xperia_z3__bootloader_degrades_its_camera-news-9831.php
I wonder if it affects the M2 as well.
In any case, it's not as useless as you think.
I think it affects our camera, or is it just me ?

It doesn't. I took a picture before unlocking the bootloader and then another one right after unlocking - no difference in quality at least in manual mode.
Hello,
I'm new to this, Iv'e backed up the TA and wondering that if I was to unlock the xperia z3 bootloader and relock would the Camera performance permanently be affected by the unlock or would it go back to the state it was in before it was unlocked? Thanks.

If you unlock and restore the TA it will be just like before, but then I have to ask why unlock if you are going to relock immediately afterwards?
As title says, is it possible?
I tried to unlock bootloader even with message saying "Bootloader unlock: No" and it worked. I didnt expect this to happend and I've lost TA partition. Most stupid move I've ever made.
Now I'm wondering about possibility of relocking without TA. I dont really care about X-Reality, low light camera issues etc.
Just want to know will it work? I really would like to avoid hard bricking.
Any information?
Without a TA partition backup, you can't relock.
Are you sure the bootloader was unlocked? Does the phone display the warning screen when phone boots?

This is impossible. If it said it was not allowed then you cannot unlock the bootloader. I imagine that your bootloader is still locked or that it was allowed in the first place.
You will not be able to restore your TA, but i believe you may be able to relock the bootloader using flashtool without it. However, you will not get back the lost functions so you will be better off keeping it unlocked (If you really are unlocked) and using a custom ROM/kernel with the DRM restore functions.
Yes I do have a warning message at boot stage. I'm currently using Existenz ROM, have root etc. So it is unlocked. I've seen a post on this forum with information that some phones display fake message about unlocking bootloader. Thats why I have tried unlocking my phone and it worked. Before bootloader unlock: no, now it says Yes. All I had to do was open dev options, check oem unlock and debug. I'm not lying to you guys.

bootloader unlocked :no it means that state of your bootloader is locked but you can unlocked.
bootloader unlocked allowed :no means you cant unlocked your bootloader because some restriccions on your phone. Only sony can change this state.
So sorry you cant relocked your bootloader if you lost your ta you only can fix it but flashing a custom kernel with drmfix. cheers
Have you relock your bootloader. I meet same sittuation with you. I unlocked bootloader for my xz1, now i want to relock it, but it cant be done. It has bootloader unlocked allowed :no

I dont know how to relock it again
I am considering relocking the bootloader for my HTC U12+. I unlocked it a long time ago (out of habit I guess). So my phone is completely running stock without any modifications. I want to relock the phone to get widewine back to L1, so I'll get Netflix updates and such.
A few questions about relocking that I couldn't find an answer to.
1. When I relock the bootloader will it do a factory reset to the phone? I'm asking because unlocking did.
2. If later on I decide to unlock the relocked bootloader again, do I have to get another unlock-code from HTC? Or is unlocking a relocked bootloader a simpler procedure?
So I decided to do the relocking. During the relocking procedure I was being told on the screen that the phone will be wiped if I continue. It remains to be seen how I'll unlock it later on if I want to.

2. You have to to go through the HTCDev website procedure (not sure if you can reuse the previous Unlock_code.bin file).
is it possible to get "locked bootloader" instead of "relocked bootloader" and get rid of system status modified?
